Steel wool isn't necessarily your enemy if you're gentle with it - the real problem is usually that the seasoning wasn't thick enough to begin with, so any scrubbing feels destructive. I had the same sticky-bottom issue with mine, and what actually fixed it was realizing I needed to build up more layers rather than baby the pan I had. After doing some high-heat cooking with oil, the seasoning got tougher and food stopped adhering like that. For the baked-on stuff right now, try a paste of coarse salt and a tiny bit of oil, scrub gently in circular motions, then rinse and dry immediately - it's abrasive enough to lift burnt bits but won't wreck a decent seasoning layer. Does your pan smoke up pretty quickly when you heat it, or does food still seem to catch even on a well-oiled surface?
